AF Form 4089: KC-10 TOLD Card Worksheet Download – The AF Form 4089, officially titled the KC-10 TOLD Card Worksheet, is a critical document used by United States Air Force (USAF) crews operating the KC-10 Extender aerial refueling and transport aircraft. TOLD stands for Takeoff and Landing Data, and this worksheet helps pilots and flight engineers compute essential performance figures to ensure safe operations under varying conditions.
Air Mobility Command (AMC) crews rely on the AF Form 4089 (also referred to as AF IMT Form 4089) to document calculated takeoff and landing performance data derived from the aircraft’s flight manual and performance manual. It supports mission planning for the KC-10, a versatile three-engine tanker capable of carrying up to 356,000 pounds of transferable fuel and 170,000 pounds of cargo while refueling fighters, bombers, and other aircraft mid-air.
What Is the Purpose of AF Form 4089?
The primary purpose of the KC-10 TOLD Card Worksheet is to organize and record Takeoff and Landing Data (TOLD) for each flight. Accurate TOLD calculations are vital for flight safety, as they determine critical speeds (V-speeds), runway requirements, obstacle clearance, and maximum allowable weights based on:
- Pressure altitude
- Temperature (OAT)
- Runway conditions (dry, wet, contaminated)
- Aircraft gross weight
- Center of gravity (CG)
- Wind components
- Slope corrections (noted on the back of the form)
Crews use the form in conjunction with TO 1C-10(K)A-1 (Flight Manual) and TO 1C-10(K)A-1-1 (Performance Manual), or approved electronic performance tools. AFMAN 11-2KC-10 Volume 3 explicitly directs crews to use AF Form 4089 or an approved electronic TOLD worksheet for computations.
This ensures compliance with operating limits, helps prevent runway overruns or insufficient climb performance, and supports crew briefings. Slope corrections for height and distance are conveniently printed on the reverse side of the form.
Note: The KC-10 fleet has been retired from active USAF service (with the last aircraft retired around 2024), but the form and associated procedures remain relevant for training, historical reference, legacy operations, or similar tanker performance planning. Always consult the latest official publications via the Air Force e-Publishing site.
Key Sections and Fields on AF Form 4089
The worksheet is a standardized card-style form designed for quick reference in the cockpit or during pre-flight planning. While the exact layout is best viewed in the official PDF, typical sections include spaces for:
- Mission/ Aircraft Information: Date, mission number, aircraft tail number, crew details.
- Takeoff Data:
- Runway designation and length/width
- Pressure altitude and temperature
- Gross weight (takeoff)
- Wind direction/velocity and headwind/crosswind component
- Runway slope and condition
- Computed V-speeds (V1 decision speed, VR rotation speed, V2 takeoff safety speed, etc.)
- Takeoff distance required (TODR) and available (TODA)
- Accelerate-stop distance
- Obstacle clearance data
- Landing Data:
- Landing gross weight
- Approach speed (Vapp) and reference speed (Vref)
- Landing distance required (LDR)
- Go-around considerations
- Other Performance Notes: Fuel load, CG position, assumed temperature methods (if used), and any special restrictions.
The back of the card often includes quick-reference charts or slope correction tables specific to the KC-10.
Crews must double-check all inputs (e.g., weather, weight & balance) because “garbage in, garbage out” applies directly to performance computations. Errors in interpolation or failure to account for runway contaminants can lead to serious safety issues.
How to Use and Fill Out the KC-10 TOLD Card Worksheet?
- Gather Inputs — Collect current weather (METAR/TAF), NOTAMs, airfield data, aircraft basic weight, fuel load, cargo/passengers, and zero-fuel weight from load planning (often using related forms like AF Form 4095 for KC-10A load planning).
- Reference Performance Data — Use the approved KC-10 Performance Manual charts or HQ AMC-approved software. AFMAN 11-2KC-10V3 emphasizes computing TOLD with official sources.
- Calculate Takeoff Data — Determine maximum allowable takeoff weight, required runway lengths, and V-speeds. Factor in engine-out performance if applicable.
- Calculate Landing Data — Compute landing distances without thrust reversers or with specific flap settings, ensuring they fit within available runway plus safety margins.
- Document and Brief — Fill in the AF Form 4089 clearly. Review during the crew briefing. The Pilot in Command (PIC) is ultimately responsible for ensuring data accuracy and compliance.
- File or Retain — Keep the completed worksheet with flight documents as required by local procedures.
For slope corrections (runway gradient effects on height and distance), refer directly to the guidance printed on the back of the form.
Pro Tip for USAF Aircrew: Cross-verify TOLD data with electronic tools when available, but always have a manual backup. Performance planning is a core skill emphasized in KC-10 aircrew training syllabi.

Importance in KC-10 Operations
The KC-10 Extender was a workhorse of AMC, combining tanker and cargo roles to support global deployments without frequent stops. Its large fuel capacity (nearly twice that of the KC-135 in some configurations) made precise TOLD planning essential, especially on hot/high airfields or when heavily loaded with cargo and fuel.
Proper use of the AF Form 4089 contributed to the KC-10’s strong safety record over decades of service in operations worldwide. Even as the fleet transitions to newer platforms like the KC-46 Pegasus, understanding legacy TOLD procedures remains valuable for aviators studying Air Force performance planning principles.
Final Recommendations
- Always use the latest revision of supporting Technical Orders (TOs) and AFMAN 11-2KC-10V3.
- Incorporate Crew Resource Management (CRM) when computing and verifying TOLD data.
- For training or refresher purposes, practice with sample scenarios using the performance manual charts.
